Iwata Neo grip

I just got the Iwata Neo, I just find airbrushes in general too skinny and uncomfortable to hold and a bit on the slippery side. After i made the grip for my middle finger and thumb, then i felt the button/trigger didn't have a great feel so made it a few mm taller and a flat top to give some extra surface area for your finger tip to grip.

Diameter of airbrush was 11mm, air fitting on the bottom is 9mm.
